Foxnews: Oldest Sibling Has Highest IQ

Sorry Seanster, but its science. Thanks Foxnews for reporting that I am smarter than my brother. (I sure wish I was taller than him too.)

Children at the top of the pecking order — either by birth or because their older siblings died — score higher on IQ tests than their younger brothers or sisters.

The question of whether firstborn and only children are really smarter than those who come along later has been hotly debated for more than a century.

Norwegian researchers now report that it isn't a matter of being born first, but growing up the senior child, that seems to result in the higher IQ scores.
